On purchase orders, several statuses exist, e.g. avaiting prepayment, open, released and so on.

However, it is not possible to make a filtered view on purchase ordrers to see whether a prepayment has already been made. Customers needs an overview of how many which of their puchase orders, they need to prepay and which have alrady been prepayed.

Hence a suggestion is to add a status 'prepayment made' or any other relevant status.
